Summary: float parsing discrepancy

Initial Comment:
Typing "3e" or "3e-" or "3e+" to the >>> prompt
or passing them to eval all return 3, which is
reasonable.

Passing any of these strings to float() throws
a value error exception.

What's the deal?

I think float() and the parser should accept the
same set of strings representing floats.  My 
preference (at least for what I'm currently doing)
is to update float() to act like eval rather than
the other way around, but either way is consistent.

Actually, it's a lexer bug that "3e", "3e-" and "3e+" are accepted.

We'll fix the lexer, thank you!
